I started getting this error.

After reinstalling python with brew and recreating the virtualenv, the issue was resolved.

$ brew unlink python3
$ brew install python3
$ rm -r .virtualenvs/myvirtualenv
$ pyvenv-3.4 .virtualenvs/myvirtualenv
$ workon myvirtualenv
$ pip install --upgrade pip
$ pip install -r requirements.txt
...

* After running brew install python, I encountered another issue when starting vim:

    import io as _io
  File "/usr/local/Cellar/python/2.7.10/Frameworks/Python.framework/Versions/2.7/lib/python2.7/io.py", line 51, in <module>
    import _io
ImportError: dlopen(/usr/local/Cellar/python/2.7.10/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so, 2): Symbol not found: __PyErr_ReplaceException

Since I encountered this error, I uninstalled python using brew uninstall python.
